Abstract

Mathematics, essential for fostering problem-solving skills, plays a critical role in education. However, the lack of creativity and flexibility among students in solving complex problems like ill-structured problems (ISPs) in exponential material indicates significant learning obstacles. This study aimed to identify and analyze the learning obstacles faced by senior high school students and explore their creative mathematical thinking abilities when addressing ISPs in exponents. Employing a qualitative descriptive method with a Didactical Design Research (DDR) framework, data were gathered through tests, observations, and semi-structured interviews. The study involved 40 purposively selected tenth-grade students from Bandung. Findings reveal that students excel in fluency but struggle with flexibility and originality. Learning obstacles include ontogenic (limited conceptual understanding), didactic (restricted instructional variety), and epistemological (context-dependent reasoning). These obstacles impede students' creative thinking development, especially in producing unique solutions and utilizing alternative approaches. The study concludes that addressing these obstacles requires innovative teaching strategies, such as problem-based learning and didactical designs emphasizing exploration and creativity. These strategies can enhance creative thinking in mathematics, benefiting students' adaptability in academic and real-world challenges. Future research should focus on implementing and refining such designs across various mathematical topics.

Abstract

Algebraic thinking ability are important for students to master and use algebraic concepts in various situations. Students with good algebraic thinking ability will find it easier to solve real-world problems and understand more abstract mathematical concepts. This study aims to describe students' algebraic thinking ability on linear equation material. Thus, the type of research used is phenomenology with a qualitative descriptive approach. The participants in this study consisted of 37 students; six students with heterogeneous abilities (high, medium, low) were then selected. The research subjects were determined by purposive sampling based on the pattern of answers representing the phenomenon that occurred. Data were collected using algebraic thinking ability tests and interviews to fulfill the validity of the data. The results showed that: 1) students with high algebraic thinking ability can use all indicators of algebraic thinking well. 2) students with medium algebraic thinking ability have difficulty in the indicators of analytical thinking, modeling, and dynamic thinking. 3) students with low algebraic thinking ability have difficulty in all indicators of algebraic thinking, namely generalization, modeling, abstraction, analytical thinking, dynamic thinking, and organization. So, teacher efforts are needed to provide students with an understanding of algebraic thinking so that students can solve math problems well.

Abstract

Understanding a concept is not only for mastering the next concept. It is the foundational skill used to solve mathematical problems. This study aims to explore students' conceptual understanding.This research is qualitative research with phenomenology. The participants in this study consisted of 18 eighth-grade students from one of Bandung's private secondary schools. After the students were given the test, six students were selected as research subjects. This aims to ensure that data can be obtained thoroughly and comprehensively. Data collection techniques included tests, interviews, and observations, with research instruments comprising a test and an interview guideline. Data saturation has been achieved. The results of this study are as follows: 1) students with relational understanding are fewer in number than students with instrumental understanding. 2) students find it most difficult to use the interconnections of various mathematical concepts in solving problems. 3) students' difficulties are due to their lack of ability in the concept of basic operations and their lack of understanding of the problems. Therefore, teachers need to strengthen students' understanding of basic operations and the concepts of mean, mode, and median to effectively connect these concepts with their problems.

Abstract

The curriculum in Indonesia has continued to evolve, particularly with the introduction of the Merdeka Curriculum in 2021. In 2022, mathematics textbooks aligned with the Merdeka Curriculum were published. This study aims to analyze the probability material in the Grade 10 mathematics textbook for senior high school based on the Merdeka Curriculum using a praxeological approach. The research method employed is qualitative with a hermeneutic praxeological approach. The findings of this study are as follows: (1) the praxeological analysis identified four structures, namely task data (T), techniques (t), technology (q), and theory (Q); (2) each task T1, T2, T3, and T4 and their respective subtasks were found to utilize only one technique (t), which is perceptual, based on students’ observations; and (3) content and contextual analysis revealed errors that could lead to potential didactical learning obstacles and a lack of sub-material on compound events. Kurikulum yang terus berkembang di Indonesia, khususnya pada tahun 2021 merupakan awal diperkenalkannya kurikulum merdeka. Pada tahun 2022 terdapat buku teks matematika yang berorientasi terhadap kurikulum merdeka. Penelitian ini bertujuan untuk menganalisis materi peluang pada buku teks matematika SMA kelas X kurikulum merdeka dengan menggunakan pendekatan prakseologi. Metode penelitian yang digunakan adalah kualitatif dengan pendekatan prakseologi hermeneutic. Hasil temuan dari penelitian ini yaitu (1) analisis prakseologi yang dilakukan terdapat ada empat struktur di antaranya data tugas (T), teknik (t), teknologi (q), dan teori (Q), (2) pada setiap tugas T1, T2, T3, dan T4 beserta masing-masing sub tugasnya yang hanya menggunakan satu teknik (t) yaitu perceptual yang berdasarkan persepsi siswa melalui observasi, dan (3) analisis isi konten dan konteks masih ditemukan kekeliruan yang menyebabkan potensi terjadinya hambatan belajar siswa yaitu didaktis serta adanya kekurangan sub materi pada kejadian majemuk.

Abstract

Motif anyaman pada dinding anjung Rumah Bubungan Tinggi menampilkan pola berulang yang dapat dimodelkan sebagai barisan biner. Penelitian eksploratif kualitatif ini merepresentasikan orientasi bilah sebagai digit 1 dan 0, kemudian menganalisis periodisitas, memformulasikan aturan berbasis modulo, serta melakukan konversi biner–desimal–karakter untuk menautkan motif tradisional dengan struktur pengodean informasi digital. Hasil menunjukkan motif membentuk barisan biner deterministik berperiode tertentu yang dapat dijelaskan melalui fungsi modulo. Berdasarkan pemetaan digit–arah bilah, disusun pula model konseptual steganografi: penyisipan pesan biner melalui variasi orientasi bilah tanpa mengubah karakter visual motif. Temuan ini menegaskan potensi motif anyaman sebagai media representasi informasi sekaligus konteks budaya untuk pembelajaran matematika diskret melalui tugas bertahap (pengodean motif, identifikasi unit ulang/periode, penurunan aturan modulo, dan konversi bilangan). Motif weaving on the anjung wall of the Rumah Bubungan Tinggi exhibits repeating patterns that can be modeled as binary sequences. This qualitative exploratory study encodes strip orientation as 1 and 0, then examines periodicity, formulates modulo-based rules, and performs binary–decimal–character conversions to connect traditional motifs with the basic structure of digital information encoding. The results show that the motifs form deterministic binary sequences with specific periods that can be described using modulo functions. Based on digit-to-orientation mapping, the study also proposes a conceptual motif-based steganography model: embedding binary messages through variations in strip orientation without altering the motif’s overall visual character. These findings highlight the potential of weaving motifs as both an information representation medium and a cultural context for discrete mathematics learning through stepwise tasks (motif encoding, identification of repeating units/periods, derivation of modulo rules, and number conversion).

ABSTRACT: In mathematics subjects, reviewing the development of the curriculum in Indonesia is a step in adapting to global dynamics in the aspect of education, student needs, and demands from the development of the times. Some examples of challenges faced by the development of the education curriculum in Indonesia from time to time are the lack of teacher readiness in adopting new approaches, the gap between implementation in the field and the concept, and inconsistencies between curricula. The purpose of the study is to analyze the development of the mathematics education curriculum in Indonesia from time to time. The writing of this journal uses a qualitative research type. The findings of the study are the development of the mathematics education curriculum in Indonesia from time to time starting from the 1994 Curriculum, KBK (2004), KTSP (2006), 2013 Curriculum, and the Independent Curriculum. Reviewed from the assessment, education starts from a written exam to a formative and holistic assessment. Furthermore, reviewed from student involvement in the 1994 curriculum, passive student involvement was found until the independent curriculum experienced an increase in student involvement to become very active personally. In terms of the role of teachers, there has also been an increase in the development of the curriculum, namely starting from the dominant method of lectures, facilitators, and collaborating facilitators. Furthermore, the flexibility of the curriculum has also increased from the "Low" category in the 1994 Curriculum to the "Very High" category in the independent curriculum ABSTRAK: Pada mata pelajaran matematika meninjau terkait dengan perkembangan kurikulum di indonesia merupakan langkah dalam beradaptasi terhadap dinamika global pada aspek pendidikan, kebutuhan peserta didik, serta tuntutan dari perkembangan zaman.

Abstract

Students typically have less interest in learning mathematics because it is still seen as a challenging subject. As a result, when compared to other disciplines, the pupils' mathematics understanding abilities remained below average. The aim of this study was to find out how employing visual aids, such as PowerPoint, to teach geometric shapes to students improved their mathematical comprehension skills. This kind of study uses a random subject posttest design and is therefore quasi-experimental. The population of this study consisted of students in class VIII SMPN 1 Pagelaran; the samples were drawn using the purposive sampling technique from students in class VIII C, which was the experimental class, and class VIII D, which was the control class. The t-test, homogeneity test, and normalcy test are the data analysis methods employed. With a significant rate of0.05, the testing results for the hypothesis produced tstat= 3.2 > ttable= 1.6801. This indicates that while Ha is acceptable, Ho is denied. This demonstrates how employing PowerPoint-assisted visual aids in mathematics instruction increases students' capacity for mathematical knowledge.
